The thing about 5500M is okay for a laptop of this size, but it's in no way a very powerful GPU. Are there any scenarios in which GPU memory of 4GB would be the bottleneck? When does it make sense to get the 8GB GPU?
Good for
- Photo Editors
- (maybe) video editing (but doubt it)
- Games
- AR/VR and AR/VR development, as time progresses
"if you’re not working with highly sophisticated 3D objects at extreme resolutions, you won’t max out your GPU’s vRAM and therefore won’t see the performance benefits."
